While alcohol use and Greek Life on college campuses have often become synonymous, little is known about the rate of use or the consequences of use for sorority women specifically. Gender has been identified as a risk factor relating to substance use on college campuses; however, there is a gap in the literature concerning compounding factors that influence substance abuse, such as membership in a Greek-lettered organization. With approximately 300,000 college women involved in Greek-lettered organizations annually (NPC, 2019), little is known about the impact of alcohol use for sorority women on college adjustment. An exploration of the perception of alcohol use, the rate of alcohol use, and the consequences of use was conducted using the framework of Baker and Siryk's Model of Adjustment (1981) for sorority women. This ex-post facto design used control group matching to explore the impact of sorority membership status on college adjustment. The data was analyzed using a one-way univariate analysis of variance, a one-way multivariate analysis of variance, and a one-way multivariate analysis of covariance. The results indicated that when compared to non-sorority members, sorority members had higher levels of perceived of alcohol use, an increase in behavioral outcomes, and alcohol-related academic consequences. Overall, sorority membership had no impact on overall mental health outcomes. Sorority membership status on overall outcomes was mediated by perception of alcohol use and alcohol use.
